PH4P, PH4PT, PH4F, PH4FT pH Sensor
Brand: Yokogawa Electric Corporation
Yokogawa’s line of pH sensors has been strengthened by the inclusion of the polymer electrolyte pH sensor PH4P/PH4PT, HF-resistant pH sensor PH4F/PH4FT, pH sensor for chemical process PH4C /PH4CT, and pH sensor for fermentation PH4FE.
Like the pH sensor series, the ORP sensor series is also offered as a complete lineup with the polymer electrolyte ORP sensor OR4P, ORP sensors for chemical process OR4C in addition to standard Ryton pH/ORP sensors.
Features- Polymer Electrolyte pH Sensor PH4P, PH4PT
- Allows pH/ORP Measurement Under Severe Conditions, such as where the Process Fluid is Heavily Contaminated or Contains Sulfide Ion.
- With Polymer used as the Inner Solution, the Liquid Junction is Large (Around 1.0 mm) and there are 2 Single Pores, which Prevent Clogging.
- pH Sensor with RTD (Resistance Temperature Detector) PH4PT is also Available.
- HF Resistant pH Sensor PH4F, PH4FT
- The Special Sensing Membrane Allows Measurement of Solutions or Drainage Containing Hydrofluoric Acid.
- With Polymer used as the Inner Solution, the Liquid Junction is Large (Around 1.0 mm), and there are 2 Single Pores, which Prevent Clogging.
- pH Sensor with RTD PH4FT is also Available.
